With unlimited data, can you use Personal Hotspot i.e. wifi tethering?

So, some iPhones are grandfathered in and have unlimited wireless data. I am curious, can those people use what is variously called "Personal Hotspot" or "wifi tethering"? You know, the thing where your iPhone's wireless data is what allows your laptop to browse the internet.

Not on AT&T, if you want tethering option you'd have to give up unlimited data.. you think AT&T of all carriers is going to willingly GIVE you the ability to tether on unlimited data? NEVER gonna happen!

You'd have to jailbreak..

P.S- look at the garbage they're pulling with Facetime over 3g.. It's only available on a SHARED DATAPLAN...

You can jailbreak and use TetherMe or PdaNet or one of the other tethering apps that funnels data through the phone's apn rather than the official tethering one which cuts the chances of at&t detecting your tethering. I've used a couple GBs a month doing this and haven't heard a peep.

And when I upgraded from ios5 to ios6, the personal hotspot feature still appears to be there and can be turned on even though I'm on an unlimited plan, but I won't be using it until I can get one of the apps from cydia.

I use TetherMe for my iPad, and haven't heard a word. The only time they threatened me is when I tethered to my Laptop with my iPhone 4 back in the day and downloaded 12-13gb of movies music and games. But if you're low key about it and use it for emails browsing etc you shouldn't have a problem.
